(Karaoke software configuration)
FIG. 5 is a diagram illustrating a software configuration example of the karaoke main body 10. The karaoke main body 10 includes a detection unit 100, a selection unit 200, a storage processing unit 300, a video data storage unit 400, an editing unit 500, and a video data processing unit 600. The detection unit 100, the selection unit 200, the storage processing unit 300, the editing unit 500, and the video data processing unit 600 are realized by the CPU 11a executing a program stored in the memory 11b. The video data storage unit 400 is realized as part of a storage area provided by the storage unit 13. In addition, the karaoke apparatus 2 which concerns on this invention should just have the detection part 100, the selection part 200, and the memory | storage process part 300 at least.

[Detection unit]
The detection part 100 detects the excitement degree of the karaoke song when a singer sings.

  The degree of excitement is a specific value obtained by quantifying the excitement of karaoke singing. The degree of excitement can be detected using a known method.

  As an example, the detection unit 100 can analyze audio data input from the microphone 40a and the microphone 40b, and obtain a total value of the sound volumes (dB) as the degree of excitement. Moreover, the detection part 100 can obtain | require an excitement degree from the degree of the motion of the face of the singer or audience image | photographed with the camera for exclusive use (not shown) (refer Unexamined-Japanese-Patent No. 2012-68373). Alternatively, the detection unit 100 captures the movement of the audience with a dedicated camera (not shown), and obtains the degree of excitement based on the number of audiences operating at a tempo that matches the tempo of the music (Japanese Patent Laying-Open No. 2015-106061). Gazette), the degree of excitement is not determined by the number of audiences, but the degree of excitement can also be obtained by the difference between the tempo of the music and the motion tempo of the photographed audience.

  The detection unit 100 outputs the detected degree of excitement to the selection unit 200. In addition, the detection process by the detection part 100 can be performed continuously from the start of karaoke singing. At this time, the detection unit 100 may always output the detected degree of excitement, or may output a new value of the degree of excitement to the selection unit 200 only when the degree of excitement changes. Alternatively, the detection process may be intermittently performed at a predetermined timing (for example, every predetermined interval from the start of performance).

[Selection part]
The selection unit 200 compares the degree of excitement detected by the detection unit 100 with a step value set for each camera stored in the storage unit 13 and selects a specific camera from a plurality of cameras.

For example, assume that the detection unit 100 detects a value of 83 dB as the degree of excitement. In addition, it is assumed that the step values of the table shown in FIG. 2 are set in the cameras C _{1 to} C ₅ . In this case, the selection unit 200 compares the volume 83 dB with the table, and selects the camera C ₃ in which the step value corresponding to 83 dB is set as a specific camera. The selection unit 200 outputs identification information for identifying the selected camera (specific camera) to the storage processing unit 300.

[Storage Processing Unit]
The storage processing unit 300 causes the video data storage unit 400 to store video data from the selected specific camera.

For example, it is assumed that identification information of a specific camera C ₃ is input from the selection unit 200 to the storage processing unit 300. In this case, the storage processing unit 300 switches the switching circuits (not shown) of the cameras C _{1 to} C ₅ provided in the karaoke apparatus 2, and only the video data from the camera C ₃ is output to the video data storage unit 400. So that The video data storage unit 400 stores the input video data in time series. In this way, by storing only video data from the camera selected based on the degree of excitement, it is possible to acquire video data reflecting the excitement during singing (video data at the time when the degree of excitement is detected). it can. Further, in this example, video data received from a camera other than the camera C ₃ (camera C ₁ or the like) is not output to the video data storage unit 400. Accordingly, the amount of data stored in the video data storage unit 400 can be suppressed.

[Editorial department]
The editing unit 500 edits the video data stored in the video data storage unit 400 for each song sung.

  For example, when the singing of a certain music is finished, the editing unit 500 reads the video data obtained during the singing of the music from the video data storage unit 400, and edits the video (moving image) by connecting them in time series. I do. Each video data reflects the degree of excitement during singing. Therefore, the edited video is a moving image that is rich in changes that are switched by the excitement of karaoke singing. Note that video editing can also be performed on the server (not shown) side.

[Video data processing section]
The video data processing unit 600 displays a video based on the edited video data on the display unit and / or uploads the video data to the server.

  The video data processing unit 600 can control the display processing unit 15 to display a video (moving image) based on the edited video data on the display of the display device 30. Alternatively, the video data processing unit 600 can upload video data (including video data edited by the editing unit 500) to a server (not shown). In this case, only the video data selected according to the excitement among the video data obtained from a plurality of cameras is transmitted to the server. Therefore, the amount of data transmitted to the server can be reduced as compared with the case of uploading video data from all of the plurality of cameras.

== About the operation of Karaoke system 1 ==
Next, a specific example of the operation of the karaoke system 1 in the present embodiment will be described with reference to FIG. FIG. 6 is a flowchart showing an operation example of the karaoke system 1. In this example, it is assumed that the table shown in FIG. In addition, it is assumed that the singer X has selected a mode for photographing his karaoke song and uploading video data to a server (not shown) via the karaoke apparatus 2.

The singer X selects an arbitrary piece of music and starts karaoke singing (start of karaoke singing. Step 10). Along with the start of karaoke singing, the plurality of cameras C _{1 to} C ₅ shoot the singer X under different shooting conditions (photographing the singer. Step 11). Video data obtained by shooting is transmitted to the karaoke apparatus 2.

  The detection part 100 detects the excitement degree of the karaoke song when the singer X sings (detection of excitement degree. Step 12). The detection unit 100 outputs the detected degree of excitement to the selection unit 200. In this example, it is assumed that the detection unit 100 continuously detects the degree of excitement until the singing of the singer X ends.

  The selection unit 200 compares the degree of excitement detected in step 12 with the step value set for each camera, and selects a specific camera from a plurality of cameras (camera selection, step 13). The selection unit 200 outputs the identification information of the selected camera (specific camera) to the storage processing unit 300.

  The storage processing unit 300 causes the video data storage unit 400 to store only video data from the specific camera selected in step 13 among the video data received by the karaoke apparatus 2 (storage of video data; step 14).

  Here, when there is a change in the degree of swell detected by the detection unit 100 (whether a new degree of swell has been detected or not in step 15), the karaoke apparatus 2 is based on the newly detected degree of swell. Steps 13 and 14 are executed.

  Thereafter, when the singing is finished (in the case of Y in step 16), the editing unit 500 edits the video data stored in the video data storage unit 400 in step 14 in time series (editing of video data, step 17).

  The video data processing unit 600 uploads the video (moving image) edited in Step 17 to the server (uploading of video. Step 18).

  Thus, according to the karaoke system 1 which concerns on this embodiment, the video data according to the excitement of a karaoke song can be acquired. Also, the karaoke system 1 can provide a video with more variety reflecting the exciting situation by editing such video data. Furthermore, by selecting only video data corresponding to the excitement from video data obtained from a plurality of cameras, the amount of data stored in the video data storage unit 400 can be suppressed.

== Modification of Embodiment ==
In the above example, an example in which different step values are set for each of the plurality of cameras has been described. However, the present invention is not limited to this.

FIG. 7 is a table showing examples of shooting conditions and step values set for each camera. In this example, there are two cameras (camera C ₂ and camera C ₃ ) that have the same step value among a plurality of cameras.

  In this case, the selection unit 200 can alternately select two or more cameras as specific cameras under a predetermined condition.

  The predetermined condition is a condition for alternately selecting one camera (specific camera) from two or more cameras, for example, a predetermined time.

As a specific example, if the detector 100 detects the sound volume 80 dB, selecting section 200 first selects the camera C ₂ as a specific camera. Subsequently, the selection unit 200 selects the camera C ₃ as a specific camera after a predetermined time (e.g. 10 seconds). The selection unit 200 repeats this process until, for example, a change occurs in the degree of excitement detected by the detection unit 100 (until a different camera is selected as a result of comparison between the degree of excitement and the stage value).

The storage processing unit 300 causes the video data storage unit 400 to alternately store the video data of the camera C _{2 and} the video data of the camera C ₃ every predetermined time.

The video data stored in this way produces different videos even at the same excitement level. When this video data is edited in chronological order, for example, in the above example, the upper body up video from 45 degrees obliquely (video by the camera C ₂ ) and the video of the entire singer (video by the camera C ₃ ) are 10 The video (moving image) is switched every second. Therefore, even if there is little change in the excitement of karaoke singing, it is possible to provide a video that is rich in change.

  The said embodiment etc. are shown as an example and do not limit the scope of the invention. The above configurations can be implemented in appropriate combination, and various omissions, replacements, and changes can be made without departing from the scope of the invention. The above-described embodiments and modifications thereof are included in the invention described in the claims and equivalents thereof in the same manner as included in the scope and spirit of the invention.
